摘　　要：生物被膜是细菌在环境中的主要存在形式,是具有三维结构的微生物群落及极强胁迫耐受性的特殊生态。在食品加工及贮藏过程中食源性致病菌生物被膜易引起消毒逃逸及细菌污染,进而造成毒素积累或食品变质,威胁消费者健康安全。在食品工业中,预防、抑制和清除食源性致病菌生物被膜是保证食品微生物安全的关键。因此,迫切需要找到高效阻控细菌生物被膜形成并有效清除生物被膜的方法和策略。本文综述了食品工业中生物被膜污染的现状及其胁迫耐受机制,并有针对性地讨论了食品加工领域中生物被膜阻控技术,有助于更清晰地认识由生物被膜造成的食品安全风险,为研发高效绿色的生物被膜清除技术提供了理论依据。Biofilm is the main ecological form of bacteria in the natural environment,which is a three-dimensional structured microbial community.Importantly,biofilms empower the tolerance of encased sessile bacteria to various adverse stresses.In the food industry,foodborne pathogens can form biofilms during food processing and storage,which easily cause disinfection escape and bacterial contamination and lead to toxin accumulation and food spoilage,thus threatening the health of consumers.The prevention,inhibition,and elimination of bacterial biofilms are of great importance for ensuring microbial food safety.Therefore,it is urgent to explore efficient strategies and methods for the detection,prevention,and removal of bacterial biofilms.This review summarized the current advances in biofilm studies in the food science area,including biofilm contamination in the food industry,the mechanisms of biofilm-associated stress tolerance,and elimination strategies,which helps to better understand the food safety risks caused by biofilms and provides a theoretical basis for the development of green and efficient biofilm removal technologies.
